SPECXFICATION forming part of Letters Patent No. 4:09,446, dated August 20, 1889.

Application led Mey 22, 1889. Serislllo. 311,698. (No model.) y

`To @ZZ whom, it may concern/f pump much of Be it known thatl, IlIRAM XV. BLAISDELL.,21 citizen of the United States, residingv at Yuma, in the ceuntyoi' Yumal und Territory ot' Arizona, have invented certain new and useful improvements iniethods of Sinking Wells; und i do hereby declare the following to be u.

full, elettr, and exact description of thcinventiem such is will enable others skilled in, the nrt to'whieh it nppertnins to make and use the sume, reference being' had to the 'necoin pzinyL ing d rawings, und to letters or figures of refer ence nnirli'ed thereon, which form :t part of this specification.

This invention relates to the construction of wells; und it consists in a novel method of sinking und. tubing4 the sume.

llitherto it hns been found very diilieult to et stream ol witter from .fine sund without drafting the sund with the wat ter, und the use et' et drive-well point is necessziry. Thisisnot pructicnblein manyplnces on account of streaks of clziy,should such oeeur. Peints, so culled, tre also limited in capacity.

My invention, in brief', consists of sensing, which is iirst sunk until the requisite depth is reached or the flow oi' witter secured. l then introduce :t i'ilfter-pi1 e ot' Somewlntt less diameter than the casing, while :is the lutter is witlulrnwn `eonrsestml is poured in to fill the space which new exists between theiltcn pipe und the surroumling earthy struts. Atter the rt-:m'ofnl of the casing t suction-pipe is introduced 'within the filter-pipe und the well is in rezuliness for operation. Byt-his tu rn ngi-ement :t large suctioirsu rlfztee or extended point, as it muy be termed, is provided, und the Well cnn be sunk in localities where other methods would l'nil.

Minor details ot this intention will be hereinnlter described.

'lhe drawings represent, in Figure l, t Vertien/l longitudinal. seetionnl elevation oi dwell luider my method before removal ol' the eatsing ind with the eem-se snnd in pluee. Fig. 2 is n similar View' with the ensing removed. Figs. 3 :tnd if :tre respectively irnnsverselse@ tionsof Figs. l tud 2.

.i .s before premised, the sinking` ofwells by menus oi' drive-well points is :it-tended with difficulty, and even when successfully accomplished the points :tre of limited capacity. Again, in very ne sand a driven-well point is a necessity. i

To carry out my invention I first sink u welhcztsiiig Artesinn wells, and composed of flush-jointed pipe'sections of the `requisite diameter. This casing is sunk until the desired depth is reached :md :t sul'iicient water-supply obtained. A second pipe 3 is now introduced, styled the iillenpipe The lot-ter is of it diameter somewhat smaller thun the outer ons,- ing,` i2, and is perforated forti certain dista-nee et its lower extremity. This perforated pori tion l may be made in various ways; but preferfibly the pipe is pierced with e. series ot' smell holes 5, after which this portion is coveed with brass Wire-cloth vof iine mesh. Thus itis evident the point of the lilter-pipe may 2 after the manner employed tei"zA be of :my length desired-in fact, equal to the i thickness of the struts through which the water is flowing. Exizeriorly of the filter-pipe, und prior to its introduction Within the wellcnsing 2, n number of blocks 7 7 are secured exteriorly at points about the filter-pipe at in-y tervals of ten or iifteen feet. These blocks ure only tempomrily secured, and ure intended to serve the purpose of centering` the lter-y pipe duringl the operation of drawing the cusing` und the introduction ot' the coarse sand. After the filter-pipe is ready lengths und introduced within the bore of the well-easing 2, it being understood that the iilter-pil'ie is closed at the bottom by :t solid plete 8, to prevent the entrance of sund or4 othier iine nntteriztl, and when in position rests on the bottom of the boring. flret'ernbly course sand or other filteringl mnterinlis now poured in between the casing i und filter-pipe 3,when the outer casing mty be wilhdrmvn a short distance, the sund :it once filling the spa-ee occupied by seid easing. This send or other substance, which muy be impervious to witter, :is hereinafter explained, is introduced in small quantities at a, time to prevent the Withdrawal of the ilterpipe,wliich wouldfoll low with the casing 2 put in at one time.

,Qo obvinte 'the objections whiohlm'iglit arise frourfuee waterY "entering and finding its were too much sund itis made up in IOO .ter from anynndesirahle str. la reaching the suction-pipe, I propose to insv rt a tamping of yelay or otheil analogous material, by which the flow of such water to the source of supply may be estoppe'd at any point along the filterpipe. 'In Fig. 2l have indicated Such tamping at `12 to exclude surface water from the water to-be supplied; but, as before premised, such tampingmaybeloeated at any point along the filter-pipe to ent ott' undesirable waterflow. Then the outer easingis entirelv withdrawn, as shown in Fig. 2, the well is completed, with the exception ofthe suction-pipe 10. The latter is represented as extending nearly to the betteln of the filter-pipe topre- Vent the tendency of the latter to till up. By this method a well can be sunk in any soft material, and eanlie furnished with a point to suit the flow of Water. A further ad vantage is that a well of this description can be made in localities wherea driven well cannot he obtained.

Theexpense is not large in inaking them, and in very line sand or in quieksand a large stream of water is readily attainable.

lVhat I desire to claim iS- 'lhe method of constructing wells which consists in sinking an outer easing,inserting a perforated pipe of lese diameter therein, filling the existing space entirely or, in part with samlm'ithdran'ing said outer caiiirg, and nally placing a suction-pipe interior-ly of the filter-pipe, substantially as herein specified.

In testimony whereof l aiiix my signature in presence of two witnesses. A
